Forecasting with Surface Weather Charts

Given that we know the weather associated with common features on a surface weather chart, for example:

  • cold front - narrow band of showers
  • NE of warm front - light/moderate wide spread precip.
  • warm sector - hot, humid
  • etc.

if we can predict the movement of these feature based on its previous motion, we can then make a forecast with this information.

So, determining movement of weather systems is quite important for forecasting.
